Quick Answer
For a basic urban get home bag, the minimum amount of water is 1 liter (33.8 ounces) per person per day, considering 8 hours of moderate physical activity.
Urban Water Rationing
When preparing a get home bag for urban environments, water rationing is crucial due to weight, space, and logistical constraints. A 1-liter water bottle is a suitable container for a get home bag, providing an adequate supply for a person with moderate physical activity for 8 hours. Aim for a total of 1 liter per person per day, with half a liter (17 ounces) used during the day and the other half for nighttime hydration.
Water Purification Options
In urban environments, water sources might be scarce or contaminated, necessitating water purification techniques. In a get home bag, consider including water purification tablets or a portable filter that can treat up to 1 liter of water at a time. Some options include Sawyer Mini, LifeStraw, or MSR TrailShot. Always prioritize water purification over the availability of bottled water.
Emergency Rationing Strategies
While aiming for 1 liter per person per day, consider incorporating emergency rationing strategies in your get home bag. This might include: limiting water intake to critical moments, using food with high water content (e.g., fruits and energy-rich snacks), and incorporating hydration-rich foods like coconut water or electrolyte-rich supplements.
